Not really.
The administrators and teachers may be expert in educating kids in general but we, the parents are expert in our own kids. As long as scores, results, benchmarks to back you up, and the kid has not been challenged and bored, I would do it all over again.
It seems like you were successful and the teacher might have agreed that your DD does not need repeating. Kudos to you and the teacher!
I would send a nice thank you e-mail/ letter to the administrator/ teacher. Everybody loves to be appreciated.
